Phenomenological study of the densification behavior of Aluminum-Nickel powder mixtures during cold isostatic pressing and differential hydrostatic extrusion

► Compaction of pure Ni and pure Al proceeds under two consecutive regimes. ► Compaction of mixtures display three consecutive regimes. ► Above 400 MPa residual microstrain of compacted sample is more significant for Al. ► Co-extruded Ni -Al mixture display a strong texture but only for Al.
